SPECIFICATION forming part of 'Letters Patent N0. 564,882, dated 'July 28, 1896.

Application filed March 7, 1896.

To a/ZZ whom it may concern,.-

Be it known that I, WILLIAM S. HAMM, a citi- Zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bicycle Lamps or Lanterns, of which the following is a specification, reference beinghad to the accompanying drawings and to the numerals marked thereon.

This invention has especial reference to a lamp or lantern for use with a vehicle of the bicycle class, and which is provided with a front lens for concentrating and throwing forward the light, and with 4side glasses.

This invention has for its object the production of a lamp or lantern, of the character mentioned, which shall be cheap in construction, neat in appearance, and eective in operation, and shall provide a clear and smokeless flame, the light from which shall be strongly reiiected forward and exhibited at each side.

The invention also relates to means whereby the air necessary to support combustion is eectively admitted to the burner, thereby producing a steadyr flame; whereby the products of combustion are rapidly and wholly permitted to escape; whereby the reiiector is made removable from the body of the lamp, in order that it may be kept burnished and bright; and to other details of construction, herein described, whereby the general 'charvacter of lamps or lanterns of this class is improved.

In the'accompanying drawings, Figure 1 is an exterior view of a lamp or lantern embodying my invention. Fig. 2 is a vertical section thereof. Fig. 3 is a horizontal section on the line x x of Fig. 2. Figs. 4, 5, 6, and 7 represent detached details.

Similar numerals of reference indicate similar parts in the respective figures.

1 is the outer case of the lamp, which, as here shown, is in the main spherical in form, although it may be otherwise shaped.` At the front of the case is an outwardly-daring tube or support 2, the interior surface of which is highly burnished. The ring 4, supporting or framing the front lens 3, is hinged to the outer part of the tube orvsupport 2 -as hereinafter described.

and carries a spring-catch 5 to hold the framed Serial No. 582.261. (No model.)

lens in a closed position. The part of the ring 4 in which the lens 3 is immediately placed is divided or split, the separated ends being provided with lugs 8 9, the latter of 55 which is, threaded and serves as a nut for a screw 10, the action being such that by tightening the screw the ring is caused to bind the lens and maintain it securely in place. It is also obvious that the ring may be loosened 6o upon the lens should occasion require this to be done.

At each side of the outer case 1, and preferably in the central horizontal plane of the lamp, are the side signals 11 12, consisting of 65 colored glasses or jewels 13 and 14, framed The glass 13 is mounted in an annular frame l5, which is hinged to a tapering thimble 16, provided with a threaded portion which screws into a 7o neck or ring 16a, secured to the outer case. The exterior part of the thimble projects slightly beyond the outer surface of the case 1, in such wise that the framed glass or jewel 13 may be swung orl turned upon its hinge 75 17, so as to permit access to the interior of the case for the insertion of a lighted match. The frame of the glass 13 is maintained in its closed position by means of a metallic clip 18, into which a portion of the flanged edge So of the annular frame 15 iits when occupying its normal position. The opposite signalingglass 14 is mounted in a frame 19, attached to which is a tapering thimble 20, having a` threaded port-ion which screws into a threaded neck or ring 21, slightly projecting from the outer case. Other functions of the tapering thimbles 16 and 2O will be hereinafter pointed out. The two thimbles may be alike e and with or without the hinge'.

The rear portion of the outer case 1 is cutaway and the interior of the opening is wid-v ened and threaded, as shown at 22. Within the threaded opening a frusto-conical body 23, the inner side of which is slightly concave 95 and highly burnished, so as to constitute a reflector, Vis screwed, the outer portion of the said body being iianged and having a milledV edge 24, whereby it may be readily screwed to and unscrewed from the outer case 1.

The upper portion of the outer case l is provided with a flanged ring 25, in themouth of i IOO which rests a conical wind cone or deector 26, supported by feet or standards 27, while at the top of the part 23 of the said cone or detlector is secured a cap 29. At the base of the ring 25 are a series of perforations 30.

The lower portion of the outer case 1 is in the form of a cylindrical neck 31, into which the upper part of the oil-receptacle 32 fits, the said receptacle, when in place, forming the base of the entire structure. The neck 31 is provided, at opposite sides, with vertical slots 33, terminating in horizontal slots 34, while the; upper portion of the oil-receptacle is furnished with projecting pins 33 34, which, in connection with said slots 33 34, unite the oil-receptacle 32 and case 1 by bayonet-joints, as will be readily understood. A plate-spring 35 partially surrounds the neck 31 of Jthe outer case, the outer end of the spring being provided with a hole 36 and an outwardly-turned finger part 37, the hole 36, when the attachment between the oil-receptacle and the case is effected, tting over the pin 33 and securing the parts together. The outward movement of the spring 35 is limited by means of a wire guard 38.

The oil-receptacle is of any ordinary or approved construction, and the shaft 40 of its wick-raiser extends beyond the outer case l, the neck or ring 31 being furnished with a slot 41, in which the said shaft rests, and which allows its passage when the oil-receptacle is to be moved downward for detachment from the case.

Within the outer case 1 is ametallic chimney 42, Fig. 4, the enlarged lower portion of which is provided with four openings for purposes to be described. The lower edge of the metallic chimney 42 rests upon the gallery 43 of the burner, so that the row of perforations 44 in said gallery is just within the base of the chimney, and at or near the base of the said chimney is also a row of perforations 45, they having the obvious function of admitting air to the ame. The upper part of the chimney 42 passes up into the interior of the cone or deliector 26.

The inner portion of the conical tube or support 2 for the lens 3 fits in the front opening of the metallic chimney 42, while the inner portion of the frusto-conical body 23, Fig. 5, as a part of which the reflector is formed, fits in the corresponding rear opening of the chimney. The two smaller openings of the metallic chimney receive the tapering thimbles 16 and 20, Fig. 6, of the respective side or signaling glasses. By this construction tight, yet readily detachable, joints are made between the front and side lenses and the reiiector, respectively, and the metallic chimney, 'which chimney serves not only to carry away the products of combustion from the flame, but also to concentrate and confine the light,so as to cause it to be eectively thrown through the front and side lenses.

removable from the outer case and metallic chimney, and that it, therefore, may be conveniently kept clean and burnished, and also that the supports of the front and side lenses may be easily removed from the outer case and metallic chimney, so as to release the latter and enable it to be removed.

The lamp or lantern is provided with a spring-support 47 ofv any ordinary or approved construction.

An important feature in my invention is the metallic chimney 42, cut away to receive the lens-supports and the inner end of the body or support carrying the removable re- Hector.V The arrangement of the air-openings, and of the cone'or deiiector and cap, and the carrying of the metallic chimney into the upper portion of the lamp-case, and near the point of exit of the products of combustion, are also important. By the construction herein described the lamp may be readily taken apart, even by persons unskilled in mechanical methods, for the purpose of inspecting or cleaning any of its parts, and as easily put together again. This may be done without unnecessarily soiling the hands, inasmuch as the exterior of the chimney and the interior of the outer case cannot be,

reached by soot or smoke, all the products of also evident that the supports for the lenses might be attached to the outer case in a manner other t-han by threaded joints, as also might the reflector, provided it were still made removable. The means of attaching the lantern-case to the oil-receptacle may be varied, the arrangement of air-apertures changed, and other details of construction altered, at the discretion of the skilled mechanic. The outer case is preferably spun,

IIO

as also are the metallic chimney and other parts; but other modes of construction thereof and changes in their shapes maybe made.

Having described my invention, I claim- 1.
